created a class that adds a TextBox with some custom properties to the toolbox. But it's only available when the project I created it in is opened itself. I'd like to have available it in the toolbox at all times.

I have a standard "class library" project with a set of classes that I use to import in almost all my new projects.
The way I work is creating a new Solution with an empty project, which is my main project, and then I add to the solution the mentioned class library project, this way I can see both projects in the Soluction Explorer and even see the library code or update it if needed. Then I write the code in my main project and I compile.
This lead me to have 2 files when I compile: file *.exe and stdlib.dll
Some cases I use the lib for very small tools that I want to redistribute in a easy and clean why, so I would like to embed the stdlib.dll generated from my class library project into my *.exe file.

View 2 RepliesI am implementing an application in vb.net about a library management system, when I add new record to the database and then close and reopen the application, the record is not there!
I googled the issue and used the text book of this course but nothing beneficial.
I can't get is to save variables permanently. For instance, say you run your project and in the source code you have Button1_click s=textbox1.text (s is the variable I declared) Button2_click s=label1.text. Say you type some thing into textbox1 then click button1. Then you click button2. Is it possible to make it that the next time you run the program the text you typed into textbox1.text last time is displayed when you click button2? I am using windows form.
View 3 Repliesat my collage we have to rename all buttons and labels to represent the type of thing the button, label or text box etc do For instance if I had an OK button I would change the Text and (Name) of the button in the Properties section from Button1 to BtnOk, if it is a Label I have to change it to LblOk etc I was wondering if there is a way to change the default (Name) Button1 to (Name) Btn1 and so on so that I only have to click on the 1 and type my description, rather than having to type the abbreviation for the type of object every-time also ?

View 1 RepliesI'm currently trying to delete data from a dataset/datasource/database using visual basic. So here is the run down: I've built a program that can add, delete, and modify customer information from an Access database and I just got the add function working. Meaning, I can now add customers to the database and it is sticking to the database. I re-ran the program and even restarted the computer the computer and the data is in the database. This works fine. However, now I want to get the delete button working but I'm not sure why it isn't deleting some of the fake entries I made just to test out the add feature.Here is the code I am using:
Dim delCompany As UMD3.CompaniesRow
delCompany = UMD3.Companies.FindByCompany (NOT SURE WHAT GOES HERE)
delCompany.Delete ()

I made a customized TextBox that I'd like to permanently add to the toolbox. But when I close the project that I created it in, my new control also disappears and I have to copy/paste or import the class-code every time I want to use it. Is there a way to get the control in the toolbox "forever"?I tried to enclose the class in a "Namespace CustomClasses" statement and changed the root namespace in the project properties to "CustomClasses", but nothing of what I tried is permanent. I prefer to store my classes in a "real" root namespace, in the same root as the microsoft and system namespaces.
View 4 RepliesIm using the webbrowser control in my application, but i want to permanently change the user agent when im navigating to sites.
I have tried the extended use of the .Navigate function for the webbrowser, but when the user navigates the browser, or when im beeing redirected by the site it goes back to the vb user-agent info.
Alternatly: Is there any way to catch the postinfo and http headers when the webbrowser control navigates to a new url?
I need to permanently store a string or maybe a object in my application. And yes, I have tried the application settings (My.Settings).
My.Settings.something = "hi" will save "hi" into something, and when i use msgbox to output the data, it works. The thing is; when I copy my application to somewhere else on my computer it is gone. I guess the settings is saved to some file at the filesystem, and when I move my file it also creates a new settings file. How can I store a string inside my application, and also move the application later on?

View 3 RepliesCreate a project that contains a Pet class. Each object will contain pet name, animal type, breed and color. The form should contain text boxes to enter the information for the pets. A button or menu item should display the pet information on a separate form. Hint: Use a ReadOnly property on the input form to pass the object to the second form.
What I have done so far is create a new class with the name Pet and have instantiated each object with readonly property. I have also created another form where the information entered by the user will be displayed. Guess I kinda need to know what would be the next step? And I want to ensure what I have done so far is correct.
